Thule Arcos Rear Mounted Cargo Box 

Anyone use this with a Tesla model Y? How was supercharging with it?

Unfortunately, only the Thule has this "aerodynamic" tow box; all others that I saw are big bricks, which are not good against the aft turbulent air, even if they may increase it. But the Thule is a bit overpriced, and there is nowhere I can just rent for a week or so. I don't want to pay for 1200-1400 euros for a box and the mount that I use - maybe - 1 time per year. If I can rent, I will let you know how it is on Ampera-e (European version of Bolt) or/and Polestar2)

Absolutely great and accurate analyze of aerodynamics, and the difference between a roof cargo box, and a hitch mounted cargo box!
